First time I ever touched a digital piano, in the past I had good upright pianos and a Yamaha C3 grand piano. So the Kawai CN301 is overall a great piano considering its price and the value it offers, I cannot complain there. I put 4-stars because I had expected the keyboard to be heavier as in touch, so it's still a good keyboard for playing casually, but as for serious study of music(conservatory level) I don't recommend it, maybe the Kawai CA series are suitable (although I never tried them). The sound quality is excellent on the SK-EX samples, that's the reason I bought the new model because of the update with this sample and it's the best one for a mid-ranged digital piano. I don't like at all the other sound samples as for playing classical music, they all sound unnatural and it's like there is a big "switch" between low keys and upper keys and I found them imbalanced and it was easy to recognize the sound as a digital piano, but the SK-EX sample is really a good one! The sound max volume is a bit lower than my expectations, but it's fine. The assembly didn't involve much work, but there was no paper dedicated to it. I later found it on the rear end of the user manual, it should had been on the first pages, or better a separate instruction sheet just for assembly! For the rest I'm happy, but only the test of time will say if it's a good piano.
